what about Shineray X2-300? it's carb version (I guess Jialing, Qingqi and Benelli all are EFI). possible to find slightly used with price around 10-12k. not sure about reliability, maybe ShuBen can tell his word as an ex-owner.

Currently I owe one Jialing JH200-8, which is street version of JH200GY with same engine. also my mate owe Qingqi QM200 motard version. both are well build motorcycles, but Jialing's EFI and engine performance are slightly better. although, both are air-cooled and low on hp.

Also I owe one JH600, which is totally different level and good bike to all-around in China (a bit heavy). Used one you can get for around 15k.

now I am going to get X2-300 for fun ride in Qinghai.
